USB-Serial Adapter (PL2303) Port Speed

From: Jacob S. Barrett <jbarrett_at_amduat.net>

I am attempting to use a PL2303 cable to my cell phone as a modem.  All works 
fine under Windows at port speed of 115200.  It works fine under FreeBSD at 
19200, but nothing higher.  When I set a higher port speed, 38400, 57600 or 
115200, the ppp chat session times out on the first AT command.  I have done 
some googling and found that others are using the PL2303 at 115200 in FreeBSD 
so I am wondering if I have done something wrong or if it is currently 
broken.  Is there any configuration that needs to be done on the uplcom 
driver to get it to work at higher speeds?  I know that is possible that the 
problem insn't with the cable but with the phone, but the fact remains that 
it works under Windows (2K and XP), so there is something different on 
FreeBSD.  I haven't had a chance to test under Linux yet.  I see that the 
uplcom driver checks for a debug OID to see if it should do debugging, but I 
can't find the OID that it is looking for in sysctl.
